RAILROAD-TIE.

To all Who/n, it 11mg/ conc/rfi Be it known that l, Hoirvrio (l.Honor-I- rox, a citizen or' the United States ot' America, residing atGreen Bay, in the county ot `Brown and State of lliseonsin, haveinvented certain new and uset'ul Improvements in lailroad-Ties, oi whichthe following is a specification, reference being had therein to theaccompanying drawing.

This invention relates to improvements in railroad ties and has for itsobject the production of a practically indestructible tie provided withshock absorbing end block or rail beds.

A further object of my invention is to provide a tie with detachableshock absorbing ends, which ends may be quickly and readily detached andreplaced without disturbing the tie proper and without making itnecessary to replace the entire tie.

Heretofore in railroad ties' of this nature, which have been constructedthroughout of concrete, molded in a variety of forms, the rigidity andnon-shock absorbing of the material used, causes the tie to crack whichentirely destroys the tie, and in several instances caused disastrousresults. By the use of my improved tie, danger from this source isentirely eliminated, the end blocks being composed of a fibrous materialpreferably wood which serves as a bed for the rails and to which theyare attached, are joined together vby an interposed block of somesuitable adhesive material preferably concrete. It will be seen that bythis arrangement, the wooden bed blocks will etliciently absorb theshocks without danger of cracking the interposed concrete tie.

W ith these and other objects in view, this invention consist of certainnovel combinations, constructions and arrangement of parts as will behereinafter fully described and claimed.

ln the accompanying drawings -Figure 1 is a perspective view-ot' my im}'roved tie, showing the shock absorbing ends secured thereto. Fig. 2 is aperspective view ot' my improved tie with the shock absorbing endsremoved. Fig. 3 is a perspective view ol a shock absorbing end piece orblocl.' which is adapted to tit to each cud of the tie. Fig. l is alongitudinal, sectional view in elm/ation of my complete tie, showingthe rails thereon..

Referring to the aceon'ipanying drawing, l represents the tie properwhich is molded Specification of Letters Patent.

preferably ot concrete and square in section. At each end of this tie lare transverse slots 2, adapted to receive the transverse tongue 3formed on the end of each of the bed blocks al. These end bed blocks #lare made preferably of wood which has been previously treated by theereosote process for preserving and are secured at meh end of the tie lso as to form a bed for the rails.

A tie bolt 5 screw threaded at each end and adapted to pass through thecentrally positioned longitudinal hole G in the tie l and end blocks tso as to securely tie and bind the said ends to the tie l when the nuts7 are tightened, forming the combination in al substantial one piececonstruction.

T he transverse tongues 3 prevents the end blocks 4l from moving out ofalinement with the tie block l, also relieving the tie bolt 5 ofconsiderable strain.

It will be seen that to renew the end blocks l while the tie is inplace, the nuts 7 on the ends of the tie bolt 5 are removed, the blocks4 may then be slid away from the tie l without disturbing the latter,newblocks can then be replaced thereon, the nuts 7 are again screwed on tothe bolt 5 and screwed home.

From the foregoing description it will be seen that a very simple, cheapand durable Shock absorbing tie has been produced, and that the bedblocks can be quickly and cheaply renewed.

Various changes in the form, proportion and the minor details oitconstruction ,may be resorted to without departing from the prin` cipleor sacrificing any ot' the advantages ot the invention as defined in-theappended claims.

Having thus described my invention, what lt claim is l. A tie ot theclass described, comprising 'a rectangular block composed ot plasticmaterial, shock absorbing means adapted to t'orm a bed t'or railssecured at each end ot tbe said rectangular block, and a tie boltadapted to pass longitudinally through the said shock absorbing meansand rectangular block for securely binding the said parts together.

Y A tie comprising a. rectangular block composed ot plastic material,shock absorbing rail beds composed ot a fibrous material and adapted tobe secured to each end of the ,said rectangular block and a tie boltadapted to pass centrallyand longitudinally through the said shockabsorbing blocks and rectangular block together.

3. A tie comprising a rectangular block composed of plastic materialstransverse slots inthe ends of said block, shock absorbing bed blockscomposed of n fibrous material and provided with transverse tonguesadapted to fit the slots in the ends of said rectangular block, and 'atie bolt adapted to pass longitudinally through the said parts forsecurely binding them together.

4. A tie comprising at concrete rectangular block having transverseslots in the ends for binding the said parts said Wooden blocks inalinement therewith,

and a tie bolt adapted to pass longitudinally 20 through the said Woodenblocks and concrete block for ,binding` the same together;

In testimony whereof I hereunto alix my signature.
